My accountant gave me an estimate for my tax refund... Oh. My. God.
Seriously, 2006 was the craziest year in terms of finances I've ever had, in a good way. This just wraps it all together. I feel better financially than I ever have, in my entire life. Credit card debt is nearly gone, I'm banking (investing) more than ever, I'm able to buy things I want, travel, and generally not concern myself with money. It's very liberating.
And it's exactly what I need to concentrate on things that really matter, like my emotional health.
